According to the previously applied standard ISO components were identified in Designation code for components to ISO ISO – Download as Word Doc .doc), PDF File .pdf), Text File .txt) or read online. Two new technical documents have recently been published by ISO and are now available from the National Fluid Power Association (NFPA). ISO

Reference identification to ISO 1219-2 and/or EN

Sensors and solenoid coils must be represented both in the pneumatic diagram and in the circuit diagram. This mixed identification code is displayed in the following figure.

EE Mark Randall Lab This setting causes 1129-2 individual structure components of the DTs of placed Fluid functions to be displayed separately in the tree view of the DT selection dialog, each with its own icon. Preconditions You have opened a project. This functionality is only available for certain module packages. Medium code for fluid-related 1219–2 Circuit number All isoo for supplying energy are preferably identified by the circuit number 0. For this reason, the identification letters of products or the reference identifiers equipment identifiers are being used in circuit diagrams in Festo Didactic documents as per EN In the second case the next free item number is assigned to the DT H3.

Do you have any questions, suggestions or criticism regarding this representation? The components in the circuit diagrams of a control system are identified by letters.

Within a circuit, components with the same component identifier are numbered consecutively from bottom to top and from left to right. You have created a page of the type “Fluid power schematic” and have opened the page in the graphical editor.


In order to ensure clarity and good legibility, the circuit symbols in both diagrams should be identified and numbered in the same way.

For pneumatic and electric circuit diagrams the designation rules are printed in the standards ISO and EN In the tree view click the desired value behind the icon. Unfortunately different designations are used in the two aforementioned standards.

The medium code consists of letters.

Component number Each component in an electropneumatic control system is assigned a component identifier and a component number in the circuit diagram. The subsequent dialog DT selection contains a list of all the device tags of all the functions available in the project.

All pneumatic components in a control system are identified by the same system number. If only one medium is used, it can be left out. Subcounter in the dialog Settings: Every component with the exception of connecting cables and hoses is identified as in the following figure.

Components with the same identification are numbered consecutively. The identification letters are supposed to be used in conjunction with the rules for forming reference identifiers in accordance with EN The DT selection is closed.

Activate the check boxes DT: The new DT is then H5. If so, please send an e-mail to: In the case of Fluid devices identified to DIN ISO you can define during the selection whether the next free circuit number or the item number is to be determined.


The new DT is then 12192. Display identifier structure for DT selection Select the following menu items: At least one fluid device is placed on the schematic page.

System designation If several systems and electropneumatic control systems are present in a plant, the system designation must be integrated into the designation code. Product-related reference identifiers are used below. Select the circuit number with program support Double-click a Fluid device in the schematic. Select the item number with program support Repeat Steps 1 to 3 described in the previous section.

Reference identification to ISO and/or EN

This task covers D1 Compare three techniques used to construct. To have the individual identifier elements of the DT of the selected Fluid function displayed by means of icons select the tab Tree. Documents Flashcards Grammar checker.

The DT of the selected Fluid function is already marked in the list. The circuit symbols are displayed as per ISO In the opened tree view click on the value behind the icon.

The designation code contains: In the case 1219- a Fluid device already placed you have the possibility of selecting the next free device tag program-supported. Circuit diagram of a pneumatic control system — components identified to ISO In the first case the next free circuit number 2119-2 assigned to the DT H3.

Circuit diagram of an electro-pneumatic control system — components identified to ISO The following 3 fluid devices are located in a project:
